Product family key features


The PRONTO series for high power replaces the FLASH series that is now discontinued. The PRONTO models offer the same laser measurement capabilities, but with new and improved electronics that allow for data logging, more calibration points and USB connection for data transfer and charging the battery.

Wide Power Range

Very low noise level = wide power range with just one device

No-Wait Measurements

5 seconds measurements allow for very short cooling time (all models except PRONTO-3K)

Easy Operation

Color touch screen display

Large Aperture

55 mm aperture to accommodate large beams


  • All-metal body
  • High damage thresholds

Advanced Features

Data logging and data transfer to PC

Compatible stand



    USB cable for MAESTRO, U-LINK (USB), and PRONTO.

Versatile absorber suitable for most applications

Our H absorber offers a spectral response that is both broadband and spectrally flat, making this power detector a versatile solution that can cover most laser power measurement needs. Our proprietary manufacturing method also gives this absorber good damage thresholds, for both average power density and energy density. It has a high absorption capacity and, therefore, generates a relatively low percentage of back reflection.

Customers enjoy:

  • Useful for measuring a wide range of lasers
  • Low risk of damaging the equipment
  • Allows fast rise time

Leverage serial commands

Use our serial commands to communicate directly with the meter without using Gentec-EO's software. You can do so using a terminal emulator software, like PuTTY, or you can just integrate them directly into your own software. All essential functions of the meter are covered by a command. Refer to the user manual of the meter for the list of all commands available.


  • Build your own software
  • Suit your unique laser application requirements
  • Automate your measurements


Traceable calibration provides the ability to trace the readings of laser output measurements to known international measurement standards determined by the National Institute of Standards and Technology (NIST). This ensures that the measurements taken by the instruments are reliable and accurate.

Benefits include:

  • Make valid comparisons of measurements taken by other instruments inside and outside your organization and over time
  • Comply with regulations or conform to industry standards
  • Avoid costly measurement mistakes in your operations
  • Improve customer confidence in your laser systems
  • Ensure laboratory experiment validity
  • Demonstrate measurement accuracy easily with the calibration certificate we provide
